colour is pale, yellowish-brown, and there is an irregular black spot on the upper part of the
erase of the posterior pair, and a curved one at the extremity of the femora of the anterior
pair, on the under side; each tarsus is terminated by two curved, slightly pectinated claws,
below which there is a small scopula. The palpi resemble the legs in colour, and have a few
black spots on the cubital, radial, and digital joints, in front. The abdomen is oviform,
convex above, projecting a little over the base of the cephalo-thorax; it is clothed with black
and short, hoary hairs, and is of a fulvous colour, with curved, transverse, oblique rows of
black spots, more or less confluent, extending from the upper part to the sides; and on the
under part numerous black spots are distributed without regularity; the branchial opercula
have a pale-yellowish tin t; and there is a longitudinal, black streak on the upper part of each
superior spinner.
In October, 1853, an immature female of this species, which is nearly allied to Salticus
frontalis and Salticus reticulates, was received from the Rev. Hamlet Clark, who took it near
Northampton in September in the same year.

The legs are robust, provided with hairs, and with two parallel rows of large, sessile
spines on the inferior surface of the tibiae and metatarsi of the first and second pairs; they
are of a pale, yellowish-brown hue, with obscure, dark annuli at the joints; the fourth pair is
the longest, then the first, which a little surpasses the third pair, and the second pair is the
shortest; each tarsus is terminated by two curved claws, below which there is a small
scopula. The palpi resemble the legs in colour. The cephalo-thorax is large, nearly
quadrilateral, thinly clothed with hairs, somewhat glossy, depressed before, abruptly sloped
behind, and projects beyond the base of the falces, which are small, conical, and rather
inclined towards the sternum; the maxillae are short, straight, and enlarged and rounded at
the extremity; the lip is triangular; and the sternum is oblong-heart-shaped. These parts
aTe'of a yellowish-brown colour; the sternum is the palest, and the lateral margins of the
cephalo-thorax and the region of the eyes, have a brownish-black tint. The abdomen is
oviform, hairy, moderately convex above, projecting over the base of the cephalo-thorax; it is
of a pale, yellow-brown colour, reticulated and streaked with brownish-black lines, a series of
pale, yellow-brown and brownish-black angular lines, disposed alternately, and having their
vertices directed forwards, extending along the middle of the upper part; the under part is
the least distinctly marked, and the hue of the branchial opercula is yellowish-white; the
sexual organs have a longitudinal septum in the middle, and their colour is red-brown.
The male is smaller and rather darker coloured than the female. The cubital and radial
joints of its palpi are short; the latter projects a small apophysis from its extremity, on the
outer side, and is fringed with long hairs on the inner side; the digital joint is oval, convex
and hairy externally, concave within, comprising the palpal organs, which are highly
developed, remarkably prominent, the base extending to the articulation of the radial with the
cubital joint, not very complicated in structure, and are of a dark-brown colour, slightly tinged
with red.
Specimens of this minute Salticus were found among moss growing in woods on the
slopes of Gallt y Rhyg, a mountain near Oakland. Both sexes are adult in summer.

pair, -raths.
The legs are robust, especially those of the first and second pairs, and are provided with
hairs and strong, black, sessile spines; their colour is yellowish-brown, a longitudinal, black
line extending along the upper part of the femora, genua, and tibise; the anterior and posterior
pairs are the longest and of equal length, and the third pair is the shortest; each tarsus is
terminated by two curved claws, below which there is a scopula. The palpi have a yellowish-
brown hue, the digital joint being the darkest. The cephalo-thorax is nearly quadrilateral,
prominent in front, projecting beyond the base of the falces; it is covered with yellowish-
brown and black hairs intermixed, and has some long, yellowish ones below the anterior row
of ey es; a narrow, black line occurs- on the margins, immediately above which there is a
longitudinal one of a yellowish-brown hue. The falces are short, powerful, conical, and
vertical; the maxillae are straight, and enlarged and rounded at the extremity; and the lip is
somewhat oval. These parts have a yellowish-brown tint, with the exception of the bases of
the maxillae and lip, which have a dark-brown hue. The sternum is small, oval, and of a
brown colour, the margins being much the darkest. The abdomen is oviform, pointed at the
spinners, convex above, projecting over the base of the cephalo-thorax; it is densely clothed
with short, yellowish-brown hairs, interspersed with long, black ones; a faint, red-brown line
passes from the spinners along the middle of the upper part, more than half of its length, and
then separates into two diverging branches, which extend to its anterior extremity and form a
very acute angle; these red-brown lines have an obscure, narrow, whitish border, bounded
